java - Can't set values in second activity -
so i'm making simple application takes information user i.e name, address etc , puts in the textviews in next activity when put in values , move next activity there's nothing displayed in textviews.
here's first activity
public class mainactivity extends activity { public string name; public string age; public string address; public string city; public string phoneno; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_main); edittext name = (edittext) findviewbyid(r.id.edittext1); name = name.gettext().tostring(); edittext amge = (edittext) findviewbyid(r.id.agee); age = amge.gettext().tostring(); edittext address2 = (edittext) findviewbyid(r.id.address); address = address2.gettext().tostring(); edittext city2 = (edittext) findviewbyid(r.id.city); city = city2.gettext().tostring(); edittext phone2 = (edittext) findviewbyid(r.id.phone); phoneno = phone2.gettext().tostring(); final imageview d = (imageview) findviewbyid(r.id.done); d.setonclicklistener(new onclicklistener(){ @override public void onclick(view v) { // todo auto-generated method stub intent intent = new intent(mainactivity.this, second.class); startactivity(intent); } }); } @override public boolean oncreateoptionsmenu(menu menu) { // inflate menu; adds items action bar if present. getmenuinflater().inflate(r.menu.main, menu); return true; } @override public boolean onoptionsitemselected(menuitem item) { // handle action bar item clicks here. action bar // automatically handle clicks on home/up button, long // specify parent activity in androidmanifest.xml. int id = item.getitemid(); if (id == r.id.action_settings) { return true; } return super.onoptionsitemselected(item);}} here's second activity
public class second extends mainactivity { protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.second); textview n1 = (textview) findviewbyid(r.id.name1); n1.settext(name); textview a1 = (textview) findviewbyid(r.id.age1); a1.settext(age); textview ad1 = (textview) findviewbyid(r.id.address1); ad1.settext(address); textview c1 = (textview) findviewbyid(r.id.city1); c1.settext(city); textview p1 = (textview) findviewbyid(r.id.phone1); p1.settext(phoneno);} public static void main(string[] args) { // todo auto-generated method stub }} here's xml main activity

after declare intent , try sending data this
//this use key-value intent.putextra("user_name" , "your string"); intent.putextra("user_age" , "your string"); and etc.
and other activity try use
bundle = getintent().getextras(); string username = extra.getstring("user_name"); string userage = extra.getstring("user_age");
